IMPROVEMENT IN MACHINES FQR GRINDING GLASSWARE.

Specification forming part of Letters Patent No. 185,227, dated December 12, 1876; applieation'filed October 21, 1876.

To all whom 'it may concern.-

Be it known that I, JONATHAN HALEY, of Rochester, Pennsylvania, have invented certain new and useful Improved Grinding, Punting, and Flatting Machine for Glassware, of which the following is a full, clear,

and exact description, reference being had to scribe the exact manner in which I have carried it out. I

In the drawings, A represents a framework, in which are bearings for the horizontal shafts B and 0. On the shaft B are rigidly secured any desired number of suitable mills D, over each of which is placed a vertical shaft, E, provided on its lower end with a convenient means for attaching a block or' plug, F, over which the tumbler to be ground is placed, as shown in Fig. 4. The vertical shafts have hearings in the cross-beams G and H of the frame-work, and are provided with the collars I, against which the horizontal levers J press to raise the shafts, as shown in Fig. 2. The bearings in the cross-beam H are provided with sleeves or bushings a, the upper portions or heads I) of which are provided with short threads, which mesh into a series of worm gears, c, on the horizontal shaft 0, as shown in Fig. 3. The heads I) are grooved at N, as shown in Fig. 3, to receive a feather, b, on the vertical shafts, and prevent the shafts from turning independently of the heads when the operation of grinding is going on. When the vertical shafts are raised by the levers J, and the tumblers are thus withdrawn from the mills, the feathers are lifted from the grooves b and the shafts cease to revolve while changing or handling the tumblers. When the shafts are again lowered to a position for grinding, the feathers engagein the grooves 12 and the shafts revolve with the heads I), which are driven by the wormgears c on the shaft 0, as above described, power being applied to the horizontal shaft B at K, and transmitted, through a proper connection, to the shaft 0 at L.

When a glass of a different shape is to be ground, the plugs F are changed to suit the shape of the glass. These plugs 1 usually make of iron or other suitable material, with rubber or cork covering.

The tumbler being placed on the plug, the shaft is lowered to the mill, and the weight of the shaft will press the tumbler on the mill sufficiently to secure the proper grinding.

The attendant will repeat the same on the other plugs until they are all in operation, when he will return to the first shaft and take off the tumbler, replacing it with another. Thus the operation is continuous.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The horizontal shaft B, provided with the mills D, and the shaft 0, provided with the worm-gears 0, in combination with the vertical shafts E, provided'with the plugs F and feathers b collar I, and sleeves or bushings a, provided with the threaded heads I), having grooves b, all constructed to operate substantially as and for the purpose set forth.
